Ms Day said the best way to save on energy costs is by switching providers.

"I switched myself using a different 9Saver offer earlier in the year, and it only took a couple of minutes. I expect to save $769 in the coming year based on my discount and my power usage, which will come in very handy this Christmas,” she said.

According to a recent series of reports commissioned by St Vincent De Paul, switching from the most expensive offer on the market to the cheapest offer on the market can save households hundreds of dollars - in some cases even more than $500.

9Saver.com.au is a cost-of-living website that pulls together all the money-saving tips and offers mentioned across Nine’s programs and presents them in one place.

Full details of the discounts, as well as terms and conditions, are online at 9Saver.com.au.
